One method of numerology involves mapping letters to numbers (A=1, B=2, C=3, ..., X=24, Y=25, Z=26), and then "digit-summing". For example, consider the name "Jacob". First, map the letters to numbers: J=10, A=1, C=3, O=15, B=2. Now add these numbers together: 10+1+3+15+2 = 31. Now go one step further and add the 3 and 1 from 31 together to get 4. 4 would be considered the digital root of the word Jacob. We can go a step further, and find the digital root of just the vowels (A=1, O=15), sum=16, digital root is 7; and the consanants (J=10, C=3, B=2), sum=15, digital root=6. Therefore Jacob has numerological scores of 4,7, and 6. The only way all three of these numbers can match is if all three scores are 9. (The digital root of all letters must equal the digital root of the sum of the digital roots of the vowels and consonants). Here is a list of baby names that are "Perfect Nines".
